As another alternative, a vapor barrier layer (14) may be attached on a surface of the insulation opposite the facing.

Description

The fibre insulation of veneer
Technical field of the present invention and industrial applicibility
The present invention relates to the fibre insulation of veneer.The insulator of veneer of the present invention provides improved calorifics, acoustical behavior and improved operability is provided in the installation process of dwelling house insulator.The insulator of veneer of the present invention also provides improved surface quality for the insulator of sealing, and improved veneer cohesive quality is provided in installation process.
Background of invention
The fibre insulation of veneer is applied to various calorifics, acoustics and dwelling house and uses.Conventional insulator generally includes the overlay coating that adheres to the fibre insulation layer.Overlay coating can be used for preventing or restriction may be by the mobile any air erosion damage that causes of the air that directly passes insulator layer at least.
The insulator of sealing is used for making the building cavity that is limited by framing component usually to insulate, and described framing component is stud, joist or the rafter wood in wall and the attic for example.Insulator is generally low-density fibrous glass insulation.The insulator of sealing can be by hammering into transverse flange framing component or the fix in position by " (friction-fit) installed in friction " or " (press-fit) installed in crimping " oversize insulator between framing component.A kind of insulator that this type of is sealed is in US patent 5,277, and shown in 955, it discloses to use and has been applied directly to the polyethylene film of the heating on the glassfiber insulation body, and discloses also and can use non-woven material, such as the layer of non-woven material.
Another patent of the insulator of openly sealing is a US patent 5,848,509, wherein uses the hotmelt that just just was applied to before applying veneer on sticking face or the insulator that non-woven covering is fixed on the glassfiber insulation body.
US patent 5,981,037 discloses a kind of insulator sub-assembly, comprises the elongated pad of fibrous insulant, and it has by using a series of at interval adhesive tapes at a certain distance to be fixed to veneer on its first type surface.
The insulation product of other veneer is used for the insulation application of HVAC equipment, duct board and other industrial insulator.An example of the fibrous insulation product of conventional veneer is open in US patent 6,444,289.US patent 6,444,289 discloses uses the atresia aluminium foil, the metal forming that adhere on the fibre insulation by adhesive to reinforce paper, foil scrim paper or polymeric material.Overlay coating be connected with insulator layer and adhesive sclerosis or solidify after, in overlay coating, form perforate.
US patent 5,783,268 and 6,270,865 fibre insulation that disclose the veneer that is used for duct board provide the air that air mass flow increases and turbulent flow reduces stream surface.The fibre insulation of this veneer also provides the smooth surface that reduces dirt and dirt accumulation.In addition, US patent 5,783,268 and 6,270,865 disclose and have used one inch or one and 1/2nd inch thick compressed fiberglass intermediate layer, and it has density is that minimum tensile strength in about 0.01 pounds per square foot, the longitudinal direction is that minimum tensile strength in 7 pounds/inch, horizontal direction is polyester/glass veneer of 5 pounds/inch.This fibre insulation is formed by the industrial standard rotation fibre technology of Owens Corning research and development, wherein melten glass be spun into fiber by the perforation spinning-drawing machine and by high-temperature gas blowing with each root fiber elongation.Fiber is then with the uncured wadding (pack) of P-F adhesive spraying with the formation glass fibre.Then veneer is put on this fiberglass pack, make that veneer only adheres to glass fibre by the incured adhesives in the wadding when wadding and veneer curing.
' 268 and ' 865 patents also disclose at the duct board external margin and formed the lapping edge to help to make fiber glass duct.But because the intrinsic difficulty of the amount of binder on the control surface, this method tends to cause the poor adhesion of felt veneer to fibre insulation.This method also tends to increase manufacturing cost, because must make the curing process optimization of fibre insulation, providing suitable bonding between felt veneer and glass fibre, rather than carries out optimization to improve the curing efficiency of the adhesive in the fiber wadding.
Except ' 268 and ' 865 patents in the disclosed method, it is also known that in this area by before veneer being applied on the uncured fiber wadding, thus be sprayed directly into adhesive on the veneer and solidify subsequently in the wadding and veneer on adhesive make the insulator of veneer.For example, US patent 5,041,178 discloses and adhesive is sprayed to veneer has wherein contacted on the interface of the upper surface of uncured wadding and lower surface.This method tends to make the lip-deep fiber of production board (finishedboard) saturated, on fibre insulation owing to produce friable surface by a large amount of adhesive of surface fiber ends in place.A large amount of adhesives on the felt also may cause the variable color of felt veneer, produce mottled or speckled surface on fibre insulation.
The fibre insulation of veneer also can form by the fiberglass pack surface that polymer is directly put on curing.US patent 5,900,298 discloses uses row's spiral spray extruder head with 1.2 to 3.5g/ft 2Amount ethylene vinyl acetate (EVA) fiber directly is expressed on the fiber wadding of curing.US patent 5,487,412 discloses a kind of duct board, and the dry solids content that comprises the plate surface is 10-20g/ft 2The applied layer of acrylic compounds foamed coating.This coating also comprises inorganic biocidal agent, for example silver nitrate.
Summary of the invention
The present invention provides veneer on one or more surfaces of fibrous insulant.This veneer provides improved surface quality, high with controlled adhesion and make easily.Veneer of the present invention comprises the adhesive that applies in advance of thermal activation.The glass fibre that this veneer can be input to fibrous insulation production line forms in the section.Alternatively, this veneer can be applied on the curing uncured wadding before or be applied on the fibre insulation of curing.This veneer can put on one or more surfaces of insulator, and can combined standard damp-proof layer veneer, and for example brown paper pitch veneer applies together.An object of the present invention is provides veneer on one or more surfaces of fibrous insulant, so that improved surface quality, high and controlled adhesion to be provided, and processing easily.Another object of the present invention provides a kind of fibre insulation of veneer, and it can be made via kinds of processes and reliable in parameters ground, can influence surface quality or the veneer cohesive to fibre insulation sharply.
